Cheap way to stop Dissimilar metals from corroding.

post #1 of 2
Thread Starter 
Hey guys! I have been reading in this section of OCN for quite some time, I rarely post here but I have noticed that corrosion is an issue many people face with their loops. I have also seen and heard all kinds of methods for dealing with dissimilar metals in their loops. Some are very creative while other's seem a little less thought out. I have yet to see one thing used in a loop. Dielectric Plumbing Fittings. For those of you who have never heard of them, They are used in household plumbing to join pipe's of dissimilar metals and mitigate the corrosion. They work amazingly well and I have only one question.

Why don't people use them? It would be pretty easy to fit them into a loop? They come in many many shape's and size's too.

When 2 pipes of dissimilar metals are to be connected (in direct contact), dielectric fittings are useful to prevent galvanic corrosion.

However, in typical PC watercooling situation, it is usually the radiator and the CPU/GPU block that might be of dissimilar metals with the coolant being the electrolyte. Therefore, a dielectric fittings are not very helpful here.
